Het onderzoek in het artikel is geïnspireerd door de casus 'platooning' uit de Grand Cooperative Driving Challenge. Er is een PreScan®/Sumulink® model opgesteld met daarin twee auto's. De voorste auto volgt een vastgesteld snelheidsprofiel, de tweede auto volgt de eerste auto waarbij de tweede auto de snelheid van de eerste meet met behulp van een AIR-sensor. De besturing van het gaspedaal in beide auto's vindt plaats met Fuzzy Logic Control in plaats van met een klassieke regelaar. Concluderend mag worden gesteld dat in dit verkennend onderzoek gebleken is dat de Fuzzy Logic Control techniek in principe werkt.

De term soft control wordt gebruikt voor een keur aan sturings- en beheersmaatregelen die organisaties helpen op koers te blijven. Ze hebben vooral betrekking op gedrag en cultuur. Uit ons inventariserend onderzoek blijkt dat er geen eenduidigheid over de definitie van soft control is en al helemaal niet over de manier waarop soft control wordt uitgewerkt. Hierdoor zijn veel uitwerkingen en meetinstrumenten voor soft control in omloop. In dit artikel vragen we ons af hoe we de kwaliteit van meetinstrumenten voor soft control kunnen beoordelen. Op basis van een aantal methodologische criteria ontwikkelen we een ordeningskader van deze instrumenten. Hiermee scheppen we helderheid in de fascinerende wereld van sociaalwetenschappelijke meetinstrumenten.

Publieke organisaties worden geconfronteerd met complexe vraagstukken, zoals structurele armoede en snel veranderende technologie. Daar adequaat op inspringen vereist veel van het innovatieve en experimenterende vermogen van deze organisaties. Uitkomsten en bijbehorende interventies staan op voorhand niet vast. Tegelijkertijd vraagt de maatschappij verantwoording van het besteedde geld aan de hand van vastomlijnde protocollen en outputcriteria. Deze discrepantie tussen flexibel acteren enerzijds en controle & transparantie anderzijds staat het adequaat functioneren van deze organisaties in de weg. In dit artikel stellen wij dat de aannames onder de besturing van, het toezicht op en de verantwoording van publieke organisaties moeten worden herzien. Deze herziening heeft tevens serieuze consequenties voor de praktijk van management accounting & control.

The purpose of this study is to explore why and how Management Accounting and Control Systems (MACS) enact and are enacted upon in the Dutch branch of nursing homes, homes for the elderly and home care. In search for answers, this study chooses an actor-network theory (ANT) perspective combined with case study research as research frames. Central theme in ANT is the theory of translation. This theory offers opportunities for a close empirical inspection of how and why MACS enact and are enacted upon by other actants in a complex set of sociotechnical relations. The theory of translation is applied in a case study research at The Relief Group (TRG), a healthcare organization which comprises a total of 10 nursing homes and homes for elderly. This case study shows how the application of MACS expands both in numbers of employees involved and in amount of information. Due to an increase in perceived environmental uncertainty and reorganization to a more decentralized model of management all TRG management levels asked, to varying degree, for broad application of MACS information in general and for non-financial information in particular. This initiated a process in which MACS did not diffuse unchanged but was manipulated and aligned with different interests of various stakeholders. At first sight, the TRG case study reveals MACS as a boundary object. In second instance however, this study questions whether this epistemological point of view, denoting the differences between the various TRG stakeholders as differences in interpretation and perception, obscuring an optimal application of MACS, offers sufficient in-depth understanding. Therefore this study draws on post ANT studies and chooses an ontological point of view, delineating MACS as different objects, enacted in different sets of relations and contexts.

Credit management neemt toe in belang. Oorzaken hiervan zijn onder meer de toenemende concurrentiedruk, nieuwe regelgeving zoals Basel II en de grotere focus op werkkapitaal in het kader van sturen op aandeelhouderswaarde. Publicaties over credit management richten zich overwegend op proces- en procedurebeschrijvingen, kredietwaardigheidsbeoordeling en auditingchecklists. Deze onderwerpen zijn ontegenzeggelijk relevant voor de analyse van credit management, maar vormen geen antwoord op de vraag hoe de control van credit management moet worden ingericht. In dit artikel wordt een praktische controlaanpak geïntroduceerd die gebaseerd is op het management control framework van Merchant en de verschillende typen kredietbeleid zoals omschreven door Wallis. Het resultaat is een aanpak die eenvoudig en praktisch toepasbaar is, geschikt is voor verschillende typen kredietbeleid en rekening houdt met verschillende typen controls.

The application of DC grids is gaining more attention in office applications. Especially since powering an office desk would not require a high power connection to the main AC grid but could be made sustainable using solar power and battery storage. This would result in fewer converters and further advanced grid utilization. In this paper, a sustainable desk power application is described that can be used for powering typical office appliances such as computers, lighting, and telephones. The desk will be powered by a solar panel and has a battery for energy storage. The applied DC grid includes droop control for power management and can either operate stand-alone or connected to other DC-desks to create a meshed-grid system. A dynamic DC nano-grid is made using multiple self-developed half-bridge circuit boards controlled by microcontrollers. This grid is monitored and controlled using a lightweight network protocol, allowing for online integration. Droop control is used to create dynamic power management, allowing automated control for power consumption and production. Digital control is used to regulate the power flow, and drive other applications, including batteries and solar panels. The practical demonstrative setup is a small-sized desktop with applications built into it, such as a lamp, wireless charging pad, and laptop charge point for devices up to 45W. User control is added in the form of an interactive remote wireless touch panel and power consumption is monitored and stored in the cloud. The paper includes a description of technical implementation as well as power consumption measurements.

1e alinea column: Ben je bereid, om het leven te ervaren en naar jezelf te luisteren? Ik hou niet van het fenomeen leiderschap. Aandacht voor dit thema is volgens mij simpelweg projectie van eigen onvermogen, een manier om met onvermogen om te gaan. Namelijk het onvermogen te accepteren dat we als mens slechts een druppel zijn in de oceaan.

This report is the final report for the FPGA accelerated PID controller, part of the Distributed Control Systems project. This project runs within the Lectoraat Robotics and High Tech Mechatronics of Fontys Hogeschool Engineering Eindhoven. The Lectoraat has the goal to develop applicable knowledge to support education and industry. This knowledge is acquired with projects run in conjunction with the industry. The report will go into detail for the software designed for this project, not the hardware design. This report is intended for follow up students working on the Distributed Control Systems project. Within this report the assumption is made that the reader is at least familiar with the terms EtherCAT, FPGA, Linux and PID controllers. However for each part a small basic introduction is included. For readers looking for the accomplishments in this project, the results are in chapter six. Following are short descriptions of the chapters in this report. The first chapter will give a short introduction to the project. It talks about why the project was conceived, where the project was done and what the expected end result is. The second chapter, the problem definition, talks about how the project has been defined, what is included and what is not and how the customer expects the final product to function and look like. The third chapter details the methodology used during this project. All the research preformed for this project will be described in the forth chapter. This chapter goes into the research into the Xilinx Zynq 7000 chip, Beckhoff's EtherCAT system, how the Serial Peripheral Interface works and how a PID controller functions. Following in chapter five the design is expanded upon. First the toolchain for building for the Zynq chip is explained. This is followed by and explanation of the different software parts that have been designed. Finally chapters six and seven provide the results and the conclusions and recommendations for this project.

The user’s experience with a recommender system is significantly shaped by the dynamics of user-algorithm interactions. These interactions are often evaluated using interaction qualities, such as controllability, trust, and autonomy, to gauge their impact. As part of our effort to systematically categorize these evaluations, we explored the suitability of the interaction qualities framework as proposed by Lenz, Dieffenbach and Hassenzahl. During this examination, we uncovered four challenges within the framework itself, and an additional external challenge. In studies examining the interaction between user control options and interaction qualities, interdependencies between concepts, inconsistent terminology, and the entity perspective (is it a user’s trust or a system’s trustworthiness) often hinder a systematic inventory of the findings. Additionally, our discussion underscored the crucial role of the decision context in evaluating the relation of algorithmic affordances and interaction qualities. We propose dimensions of decision contexts (such as ‘reversibility of the decision’, or ‘time pressure’). They could aid in establishing a systematic three-way relationship between context attributes, attributes of user control mechanisms, and experiential goals, and as such they warrant further research. In sum, while the interaction qualities framework serves as a foundational structure for organizing research on evaluating the impact of algorithmic affordances, challenges related to interdependencies and context-specific influences remain. These challenges necessitate further investigation and subsequent refinement and expansion of the framework.
